Title: System and method for the preservation of unique identity keys without encryption through a process of transactional successive transposition
Inventor: IVEY CHRISTOPHER LIAM
IPC: H04L29/06
Filed: 2003-08-08
Abstract: The invention is a system and method for positively identifying the origin of a transmitted message from a computer without requiring encrypted or secure communications.  The invention employs a method of Transactional Successive Transpositions of a pair of Authentication Keys of 256 Bytes or more in length for each correspondent. Each time a key is exchanged, it is modified using a Transform Key and the result is compared against a Reference Key. If the transposed result matches the Reference Key [301], the key is accepted as valid, and is exchanged with the Transform Key [302], which is in turn exchanged with the Reference Key. When a new Authentication Key is required to identify an outgoing message, the new Reference Key and Transform Key are used to transpose each other and create a new Derived Value [303].   Since the keys are transposed with each transaction, it is impossible to duplicate a message by intercepting the attached Authentication Key.   This is not system of encryption, but a means of identification. While it is theoretically possible to break this system, it is only practically possible if all communications between correspondents are intercepted. It not possible to share, reproduce, or publish Authentication Keys.   The system employs a Key Declaration Parser [102] to determine whether an incoming message is a Key Request, a Key Grant, or a message From an Authenticated Correspondent. If a user requests an Authentication Key, the key Request Interface [103] is involved to require a transactions or user intervention. Authentication Keys are managed using an Authentication Key inspector [104] which involves the Key Transformation Engine [105] and compares the transposed values with those stored in the Authentication Key Database [106]. Data captured from authenticated messages is passed to the target application via an Application Interface [107].

Title: Drilling flange and independent screwed wellhead with metal-to-metal seal and method of use
Inventor: MCGUIRE BOB
IPC: E21B33/03
Filed: 2003-09-09
Abstract: A drilling flange and an independent screwed wellhead provides a metal-to-metal seal that supplements the traditional elastomeric O-rings for providing a fluid seal between the drilling flange and the wellhead. The metal-to-metal seal may be achieved using a metal ring gasket or two contacting metal surfaces that are machined to required tolerances and are configured to be forced together when the drilling flange is mounted to the wellhead. The metal-to-metal seal ensures a fluid seal between the flange body and the wellhead in the event that the O-rings malfunction or are destroyed by fire.

Title: Network termination equipment
Inventor: CZERWIEC RICHARD MARION
IPC: H04L12/66
Filed: 1998-06-10
Abstract: An architecture, as well as various components, of an asynchronous transfer mode (ATM) subscriber access multiplexer (ASAM) system can be implemented using an xDSL (x-Digital Subscriber Line) using DMT (Discrete Multitone) or CAP (Carrierless Amplitude Phase Modulation) between a plurality of subscribers and a corresponding plurality of line termination equipment in a shelf that also includes network termination equipment for connection to an ATM network. The line termination and network termination equipment are interconnected by a bus internal to the shelf for providing subscriber access. Separate lowpass filters are provided at each end of a twisted wire pair between the shelf and each subscriber equipment. A shelf can be used as a hub for connecting to a remote shelf that includes the line termination equipment for connection to subscribers.      Although the internal bus of the shelf is shown in a non-redundant embodiment, an increased level of equipment protection can be provided by placing one half of a redundant equipment pair in one shelf and the other half in the other shelf and sharing network termination equipment between such shelves.

Title: Vehicle article carrier and bracket assembly
Inventor: AFTANAS JEFFREY M
IPC: B60R9/045
Filed: 2004-03-04
Abstract: A vehicle carrier apparatus adapted to be disposed on an outer body surface of a vehicle for supporting articles.  The apparatus includes support rails secured to the outer body, a cross bar spanning the support rails, and bracket assemblies secured to the cross bar.  The bracket assemblies are coupled to the support rails and include a lower locking clamp pivotally secured to the housing.  The lower locking clamp rotates between an open position and a closed position and secures the bracket assembly to the support rail when in the closed position.  The open position is approximately 180° from the closed position.  A detail within the housing contacts a first face of the lower locking clamp in the open position and a second face of the lower locking clamp in the closed position, thus preventing the lower locking clamp from rotating more than 180° between the open and closed positions.

Title: Auto-negotiation monitor system, repeating-transmission apparatus, and auto-negotiation monitor method used therefor
Inventor: YAMAUCHI TOSHIRO
IPC: H04L69/40
Filed: 2004-09-29
Abstract: Where each of switches opposed to each other detects optical-signal shutoff or optical-signal deterioration on the reception side of its port, the switch brings a link of the port down and outputs an auto-negotiation configuration code, as an LAN signal. Upon receiving the LAN signal transmitted from the switch, a repeating-transmission apparatus transmits the transmitted signal to an auto-negotiation monitor. The auto-negotiation monitor performs code analysis for the transmitted LAN signal. Where the auto-negotiation monitor detects that the transmitted LAN signal is the auto-negotiation configuration code, it notifies a monitor apparatus that "The switch detects a failure and the link is down.", as an alarm.

Title: Interface for shunt voltage regulator in a contactless smartcard
Inventor: GAY MICHAEL J
IPC: G05F1/613
Filed: 2003-07-01
Abstract: The present invention provides shunt voltage regulation by employing a rectifying means (M1-M4) to rectify an incoming signal and a current sinking means (M5-M6) to divert current from the output (o) of the rectifying means in such a way that the output voltage is maintained at an appropriate level and the modulation level does not rise above the acceptable range. This is accomplished by having two feedback mechanisms for the control of said current sinking means. A first feedback mechanism (G) utilizes a voltage dividing means (R6-R7) to generate a control voltage signal that will cause the average output voltage of the rectifying means to be equal to the a reference voltage.  A second feedback mechanism utilizes non-linear processing means (NLP; Fig. 7) and capacitors (C3-C4) to transmit part of the modulation frequency to the control (M7-M14, R2-R5) of the current sinking means, thereby keeping the modulation at the output of the rectifying mean at an appropriate level at all time.
